Graffia became unemployed as she was involved with Max Fenig. She believed in him, and stole three artifacts for him from her company as irrefutable proof of alien existence. She also recorded videos of Fenig explaining his theories. She saw him take one of the artifacts to bring to Fox Mulder on flight 549. When the plane went down, she knew he was abducted again and the artifact taken. She claimed to be the sister of Max Fenig to Mulder and Dana Scully during the investigation as per Fenig's wishes. She presented to them hundreds of letters written by her brother describing his abduction experiences. While in her hotel room, however, she too was abducted but soon returned in a hysterical state. Following her abduction, she was admitted to Northeast Georgetown Mental Health Center.
The agents eventually learned that Graffia was not Fenig's sister, but rather their relationship was more romantic in nature. Scully visited her at the Mental Health Center and encouraged Graffia to tell the truth about everything. There were three items they had stolen: Max had one, Graffia had one, and the third was at large in a Syracuse airport. Max's item had been retrieved by a UFO immediately prior to the crash of Flight 549 as Graffia's item had been retrieved when she was abducted. Mulder was able to obtain the third and final item, but it too was retrieved in mid-flight by a UFO.
